SPECXFCATION forming part of Letters Patent No. 324,567, dated August 18, 1885.

Application filed June 15, ISES. (No model.)

To all whom it may concern:

Be it known that l, ARNEY S. LAnsoN, a citizen of the United States, anda resident of Geneva, in the county of Freeborn and State of Minnesota,have invented certain new and useful Improvements in Sleigh-Knees; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being had'to the accompanying drawings, which form a part of this specification.

My invention relates to bolo-sleighs; and it consists in the improvedconstruction and combination of parts of a sleigh-knee adapted forbob-sleighs,which will be hereinafter fully described, and pointed outin the claims.

Referring to the annexed drawings, Figure lis a perspective view ofabobsleigh provided with my improved sleigh-knee. Fig. 2 is aperspective view of my invention removed from the sleigh. Fig. 3 is adetail view in perspective of the knee proper. Fig. 4 is a similar Viewof the grooved casting, which is movably secured upon the knee. Fig 5 isa vertical transverse sectional view taken on the plane indicated byline x, Figz; and Fig. 6 is a vertical sectional View taken onthe planeindicated by line yy, Fig.

The same letters of reference indicate corresponding parts in all thefigures. Y

Referring to the several parts by letter, A A represent the runners ofthe sleigh, which are of ordinary construction and form no part of myinvention.

B indicates the knee proper,which is cast in the form shown, its base Bbeing provided on its lower side with the longitudinal recess B2, toadapt it to fit upon the upper side of the runner, where it is securedin its operative position, the knee being further provided with theprojections B, to which are secured the upper ends of two braces, A A',which are secured at their lower ends to the runner on opposite sides ofthe knee, and serve to brace the same firmly.

B* represents the head of the knee, which is cast at right angles to thebase thereof and on a slight incline toward the inner side ot' the knee,the said head being circular in cross-section,butformedwiththelongitudinalshoulders Bon each side at such pointsthat more than onehalf of the circumference of the head rises above thesaid shoulders. The extremities of the head extend beyond theseshoulders, as shown, :for the purpose hereinafter set forth.

C C indicate theA grooved castings, upon which the ends of thecross-beams D rest and are secured, the said castings being providedwith the upwardly-projecting side Iianges, C', between which the end ofthe beam fits, and which serve to preventthe same from working loosesidewise. Each casting is provided on its lower side with a longitudinalconcave recess, Ct, of such a length and size as to adapt it to receivethe upper portion of the head B4 of the knee B, the casting being alsoprovided with the vertical apertures G3 at each end, through which passthe clipsE E,which secure the ends of the beams upon the upper sides ofthe castings. These clips E E are formed with the shoulders E E',located at such points that when the casting has been placed upon theknee and the clips adjusted in their operative positions, with theirlower central portion encircling the round ends of the knee-head B", theshoulders E E will bear against thelowerside of the casting C, so thatthe nuts upon the ends of the clips may be tightened to bind the ends ofthe beams firmly in position without binding the ends of the knee-headagainst the lower side of the casting so as to interfere with therocking or oscillating motion of the casting upon the rounded knee-head.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of my improvedsleigh-knee for bob-sleighs will be readily understood without requiringfurther explanation.

lt will be seen that my invention is simplein construction, andtherefore not liable to break or get out of order, while at the sametime it is very efficient in its operation.

I am aware that a sleigh-kneehasbeen heretofore constructed comprisingabase adapted to be secured upon the upper side of the runner, andformed with a rounded head extend ing at right angles thereto, androckers or l castings which support the ends of the sleighbeams, andwhich are secured movably upon IOO the said rounded heads by means ofordinary clips passing around the ends ofthesaid rounded heads andthrough the sleigh-beams, and I do not therefore claim. suchconstruction broadly; but

What I claim as my invention, and desire to secure by Letters Patent ofthe United States,

l. As an improvement in sleigh-knees, the combination of theknee proper,composed of the base provided on its lower side with the longitudinalgroove or recess, the rounded head cast at right angles to the base, andinclined slightly toward ,the inner side of the same, and having thelongitudinal shoulders, arranged as described, the casting having theupwardly-'projecting side flanges and the vertical apertures andprovided on its lower side with the longitudinal concave recess, and theclips having the shoulders formed thereon, all constructed and arrangedto operate in the manner and for the purpose shown and set forth.

2. As an improvement in bob-sleighs, the combination, with the runners,ofthe knee having the longitudinal recessin the lower side of its base,the side projections, and the inclined rounded head having thelongitudinal shoulders, the inclined braces extending from the runner tothe side projections of the knee, the casting having theupwardly-projecting side anges and the vertical apertures and providedon its lower side with the longitudinal concave recess, and the clipshaving the shoulders formed thereon, all constructed and arranged tooperate in the manner and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two Witnesses.
